Brooks B17 Narrow or B17 Narrow Imperial

Hi all,
I've got a Brooks Flyer on my flat bar Jamis Coda Sport. I'm not quite ready to put one on my cf road bike (trying to fight the weight weenie tendencies, but still), but I do want to get a Brooks for my new Jamis Sputnik (2010 631 frame model). So, I'm pretty sure I want to go with narrow instead of the standard B17. My question is whether the features off the Imperial (cut out, laces) are worth the extra cash ($135 v. $110). Thoughts?
Thanks,
Bryan

If you prefer to have a cutout saddle, then the Imperial is the one for you. IMO, the extra $25 is nothing in terms of what is comfortable and what works for your butt. Do you know if you prefer a cutout or not?
